LX570_OM_OM60L21U_(U) CAUTION■
While driving
Never move the four-wheel drive control switch if the wheels have lost traction.
Doing so may cause an accident resu lting in death or serious injury.■
When the vehicle is parked
If the shift lever is moved before the low speed four-wheel drive indicator turns on/
off, the transfer mode may not be shifte d completely. The transfer mode disengages
both the front and rear driveshafts from the powertrain and allows the vehicle to
move regardless of the shift position. (A t this time, the indicator blinks and the
buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in “P”. You
or someone else could be se riously injured. You must complete the shifting of the
transfer mode. ( P. 3 3 0 )
NOTICE■
To prevent damage to the center differential ●
For normal driving on dry and hard surface roads, unlock the center differential.●
Unlock the center differential after the wheels are out of the ditch or off the slip-
pery or bumpy surface. ●
Do not push the center differential lock/u nlock switch when the vehicle is turning
or when its wheels are spinni ng freely off the ground.

Function limitations
Crawl Control ●
In the following situations, brake control can be used to drive downhill at a con-
stant speed. However, engine control is not available when driving uphill at a
constant speed.
• When switched to second start mode. ●
In the following situation, engine control and brake control will stop temporarily.
In this event, the Crawl Control indicator will flash.
• When the vehicle speed exceeds approximately 15 mph (25 km/h).
Tu r n A s s i s t f u n c t i o n
In the following situations, the Turn Assist fu nction will stop temporarily. In this event,
the Turn Assist indicator will flash. ●
When the vehicle speed exceeds approximately 6 mph (10 km/h).●
When the shift lever is moved to “R”.■
When the Crawl Control system is operated continuously ●
If Crawl Control is used continuously for a long time, the buzzer will sound, a
malfunction notification will be displaye d on the multi-information display, the
Crawl Control indicator will go off, and Crawl Control will be temporarily inop-
erable as a result of the brake system over heating. In this event, stop the vehicle
immediately in a safe place, and allow the brake system to cool down sufficiently
until the “TRAC OFF” on the multi-inform ation display goes off. (In the mean-
time, normal driving is possible.) ●
If Crawl Control is used continuously for a long time, the buzzer will sound, the
system will be temporarily canceled, and a malfunction notification will be dis-
played on the multi-information display as a result of the automatic transmission
system overheating. Stop the vehicle in a safe place until the display goes off.

When driving
LX570_OM_OM60L21U_(U) NOTICE■
To prevent the water damage
Take all necessary safety measures to en sure that water dama ge to the engine or
other components does not occur. ●
Water entering the engine air intake will cause severe engine damage. ●
Water entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age. ●
Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differentials, transmission and transfer case, reduc-
ing the gear oil’s lubricating qualities.■
When you drive through water
If driving through water, such as when crossing shallow streams, first check the
depth of the water and the bottom of the river bed for firmness. Drive slowly and
avoid deep water. ■
Inspection after off-road driving ●
Sand and mud that has accumulated in brake drums and around brake discs may
affect braking efficiency and may damage brake system components. ●
Always perform a maintenance inspection after each day of off-road driving that
has taken you through rough terrain, sand, mud, or water. For scheduled mainte-
nance information, refer to the “Warra nty and Services Guide/Owner’s Manual
Supplement/Schedul ed Maintenance”.
